  • Publication number: 20200090767
    Abstract: Several embodiments of memory devices and systems with offset memory component automatic calibration error recovery are disclosed herein. In one embodiment, a system includes at least one memory region and calibration circuitry. The memory region has memory cells that read out data states in response to application of a current read level signal. The calibration circuitry is operably coupled to the at least one memory region and is configured to determine a read level offset value corresponding to one or more of a plurality of offset read level test signals, including a base offset read level test signal. The base offset read level test signal is offset from the current read level signal by a predetermined value. The calibration circuitry is further configured to output the determined read level offset value.

  • Patent number: 10593412
    Abstract: An indication of an initialization of power to a memory component can be received. In response to receiving the indication of the initialization, a last written page of a data block of the memory component can be identified. The last written page is associated with a status indicator. A determination is made of whether the status indicator can be read. Responsive to determining that the status indicator cannot be read, it can be determined that programming of data to the data block of the memory component did not complete based on a prior loss of power to the memory component.

  • Publication number: 20190341117
    Abstract: A temperature associated with the memory component is determined. A frequency to perform an operation on a memory cell associated with the memory component is determined based on the temperature associated with the memory component. The operation is performed on the memory cell at the determined frequency to transition the memory cell from a state associated with an increased error rate for data stored at the memory cell to another state associated with a decreased error rate for the data stored at the memory cell.

  • Patent number: 10430116
    Abstract: Devices and techniques for correcting for power loss in NAND memory devices are disclosed herein. The NAND memory devices may comprise a number of physical pages. For example, a memory controller may detect a power loss indicator at the NAND flash memory. The memory controller may identify a last-written physical page and determine whether the last-written physical page comprises more than a threshold number of low-read-margin cells. If the last-written physical page comprises more than the threshold number of low-read-margin cells, the memory controller may provide a programming voltage to at least the low-read-margin cells.
